Consensus sequences for Box A and Box B from tRNA genes in Tritryps. Sequences from class I and class II tRNA genes from Tritryps are compared to the S. cerevisiae consensus sequences (panel A). In Box A, some tRNA genes contain an extra base between positions 9 and 10 (marked with an asterisk) (see text). Conserved positions are shown in bold type. Panel B shows a comparison of Box A from selenocysteine tRNA genes from the indicated species. Conserved nucleotides are indicated with an asterisk. An A in the third position (in bold and underlined) seems to be specific to Box A from Sec genes. H represents C, T or A.
